Catalog excerpts

The ITS-90 recommends thatwater cells be made from water with substantially the isotopic composi-tion of ocean water.Ӕ Research hasshown that TPW errors associated with isotopic composition can be as large as 0.00025 C. The uncertaintycontribution from VSMOW errors inHart cells is less than б 0.000007 C. ThatВs seven micro-Kelvin!Hart offers two options for verify-ing the isotopic composition of any purchased water cell, both at nomi-nal costs. We can submit to a testinglaboratory a sample of water taken from your own cell ( after it was com-pletely manufactured, so you get avalid...
